Today I try to restore iphone with 1.1.4 firmware on it with itunes, phone was jailbreaked, when I pressed restore in itunes phone reboot and then it says restoreing iphone, iphone light up with disk itune logo on screen and picture of usb lead I then get error on computer, restore failed, now computer dont reconise iphone (unknown usb device) and iphone just shows the disk with tune logo and usb lead on screen.
Please advise how can I fix this.

if u have downgraded to 1.1.4 u should have (apple mobile device support software) which u will get after installing itunes 7.7 and then uninstall only itunes 7.7, restart ur system and install itunes 7.5 and connect ur iphone in dfu mode make sure it is connected in dfu mode and then try to restore

use ibricker to recover ur iphone
